Please name a situation Hpasp, why you deny us the Shilka, most aricraft fly higher than shilka's maximum shooting altitude except when they are landing. Also arkhangelask, remember that the SA-6 is continually receiving upgrades and will be in the Air Defence forces for a long time, only expansion opportunities are really in American SAMS, specifically the MIM-114. My guess is also that the SA-8 is secret as well.
